I was able to use keyword RegionName to specify Region Name when create OpenStack client instance with Python API. It is like:
novaclient.Client(Version, User, Password, Project_ID, Auth_URL, RegionName='RegionName')
But in the latest version OpenStack, I got error message:
TypeError: init() got an unexpected keyword argument 'RegionName'
I had to remove RegionName parameter:
novaclient.Client(Version, User, Password, Project_ID, Auth_URL)
But I do not know where to specify Region Name in my Python program. From OpenStack official document, https://docs.openstack.org/python-novaclient/latest/reference/api/index.html I cannot find any information about setting Region Name. Either with credential or keystoneauth session, no way to specify Region Name. Same to other OpenStack clients.
My question is how I can specify Region Name when create OpenStack client instance with Python API? Appreciate your answer!
You need to pass region_name as keyword argument to mention region while creating nova client.
novaclient.Client(Version, User, Password, Project_ID, Auth_URL, region_name='Region1')
Here is source reference for Nova Client class,
